Cell Surface Immunofluorescence Staining Protocol


CD19 is a 95 kD glycoprotein, also known as B4. It is a member of the Ig superfamily, expressed on all pro-B to mature B cells (during development) and follicular dendritic cells. Plasma cells do not express CD19. CD19, in association with CD21 and CD81 forms a molecular complex integral to B cell activation.

Other Names: B4
Structure: Ig superfamily, associates with CD21 and CD81, 95 kD
Distribution: Pro-B cells to mature B cells (during development), follicular dendritic cells
Function: Modulates B cell activation and differentiation
Ligand Receptor: CD21, CD81, Leu-13
